I set the east west limits on my Fortec Star Dynamic receiver and can't seem to unset them! The east limit is set at 93W. West limit is 129W. I go into antenna setup menu, then disecq 1.2, then go to set limit, it currently shows disable as the default. If i use the volume button on remote I can't move the Sg2100 motor left or right to go east of 93w. It will move to the west , not east. I've tried everything I can think of...the manual is very basic. Any ideas? Thanks! Blind
